Dear VMD friends:
    Should the qwikmd file prepared by different versions of vmd be
identical?
I hope I am wrong, but for an identical protein pdb, same condition
(explicit, 300k 0.15NaCl), the qwikmd files prepared by vmd1.9.4a12 and
vmd1.9.4a29 appear having many different places.
Would these differences generate identical simulation results? (This could
be answered by analyze trajectory files downstream..Both vmd1.9.4 version
could not repeat production simulation more than 3 in my system: ubuntu
16.04 LTS, NVIDIA-Linux-x86_64-440.82, cuda_9.0.176_384.81_linux.)
Repeated production simulation more than 3 cycles could be achieved if
using vmd1.9.3 with cuda8, which generate a qwikmd file has many places to
those of vmd1.9.4 version)
Understand these parameters one by one to tell which one makes the
difference is what I have to do now.
